GZIP Compression On - GTmetrix
Posted: Sun Dec 22, 2024 10:53 am
It should be noted that thanks to GZIP it is estimated that a file reduction of about 70% is possible , not bad, right? Furthermore, all the main browsers support it as well as the majority of the hosts , but do not rush to choose GZIP without first reading the recent counter-proposal: Brotli !
Broths
Compared to GZIP, Brotli is significantly younger : it was initially philippines phone number list released in 2013 by some Google engineers, but it only focused on HTTP compression in 2015.
This is an algorithm capable of reducing file sizes by 26% more than already known solutions , including GZIP.
Just like GZIP, Brotli also works with different compression levels , 11 to be exact: the first level with a reduced file compression, but at a very high compression speed, up to the eleventh level where the maximum file compression occurs, but specularly, at a slow speed.
Brotli and CDN: some disadvantages
It has already been mentioned that Brotli is relatively new especially compared to GZIP and this fact explains why it is not supported by all browsers or available in all CDNs . CDN stands for “ Content Delivery Network ”, that is, a network of servers designed to host static and/or dynamic content from various websites.
There are some CDNs that already support Brotli, such as KeyCDN and CDN77 , and it is essential that your origin server enables Brotli for it to work.
Although it took a while and is not as common as GZIP, Brotli is still making progress with web browsers , and once properly installed, if a browser does not support it, servers that have Brotli enabled will automatically fall back to GZIP.
